FX505DT-HN657T fans don't run every other boot

I’ve been running Manjaro XFCE for nearly a month now and I’ve noticed that the fans don’t work after every other boot.

Here’s a short summary of what I have on the laptop:

Not sure what I should do to get the fans running for every boot.

Also, does Manjaro support enabling turbo boost on my CPU?

Hello @chickengod

Seems your fans are managed by linux and not by the UEFI. The fans starts working depending on the heat. And if the heat is not high, the fans can stop completely. So I imagine that you start your laptop after a while as it was shut downed. The heat is not high and therefore fans don’t start. After a while they should start.

Since you have an ASUS Laptop, have look here:

maybe your fans indeed have a problem,idk.
but i had that impression when i moved from windows to manjaro,and it ended being that the cpu governor was set to powersave which i changed to performance,and now i can hear them ramp up.

chickengod · 26 March 2021 07:12

I see what you mean. How did you figure it out? Trying to understand how Manjaro shows the way it’s configured.

Also, is there a way to enable turbo on my CPU? I’ve set my governor to ondemand. Just wanted to check if it works well.

megavolt · 26 March 2021 08:05

As i quoted, turbo boost is enabled:

To check this the simple way, with onboard tools, open a terminal and type:

watch -n1 "cat /proc/cpuinfo | grep MHz"

Then open a second terminal let the cpu work:

for i in $(seq $(getconf _NPROCESSORS_ONLN)); do yes > /dev/null & done

You should see that the cpu freq goes up.
This kills the cputest:

killall yes

Maybe another terminal to watch the temperature:

watch -n1 "sensors | grep Core"

In general, if the Fan is controlled by the UEFI, then sensors don’t display the RPM of the fan. Conclusion: it is controlled by the OS and therefore linux.

Install this and you will get the control over your fans and RGB back-lighting via the keyboard shortcuts just like it is on Windows. We have the same laptop btw

chickengod · 2 April 2021 11:17

I’ll try this and update this.

chickengod · 2 April 2021 12:58

Tried doing it but get these messages from the terminal.

Unable to find module faustus/0.2 for kernel 5.11.6-1-MANJARO: Not found in dkms status output.
==> Unable to find module faustus/0.2 for kernel 5.10.23-1-MANJARO: Not found in dkms status output.
==> Unable to find module faustus/0.2 for kernel 5.4.105-1-MANJARO: Not found in dkms status output.

Next, I rebooted and now my lights aren’t working using FN + Up or Down arrow keys to change the RGB brightness.

Syzygianinfern0 · 2 April 2021 13:17

I think you are missing the dkms modules.

You can install it from the Pamac Manager and also make sure you select the right linux-headers version under the shown optional dependencies.

chickengod · 2 April 2021 14:52

Do I need to install this first then faustus?

I assume I’ll select the LTS kernel option?

chickengod · 2 April 2021 15:36

I can’t seem to find cputest in AUR. Do I get it from GitHub?

megavolt · 2 April 2021 23:30

This is the whole cputest:

What do you need more?

Run this and look at the taskmanager. You will see cputest there.

chickengod · 3 April 2021 01:58

I was getting this, so I thought it was an executable I needed to download.

megavolt · 3 April 2021 02:10

Ah kk… sorry. Thought i could replace yes with cputest. I tested it on my machine and it worked with cputest, however this should work:

for i in $(seq $(getconf _NPROCESSORS_ONLN)); do yes > /dev/null & done

killall yes

chickengod · 3 April 2021 02:18

I guess this is the expected result of maxing up to 3.5Ghz?

yepp, it starts on every single possible core a process and upscale it to the max frequency. That is all what it does.

Syzygianinfern0 · 6 April 2021 05:31

It depends on your kernel. Can you show the output of uname -r?

chickengod · 6 April 2021 13:49

It’s 5.11.6-1-MANJARO

Syzygianinfern0 · 6 April 2021 14:03

Then select the linux-headers package.

chickengod · 7 April 2021 09:17

That seems to work. I can see that TUF Controller shows the 3 modes and I’m able to switch it via the FN + F5 key.

However, it looks like reaching 70°C doesn’t show the fans running on the sensors.

Could that be an issue of the sensor monitoring software?
